Lots of folks use twisted wire in their work, I've noticed, not just
"wire-wrappers". Generally they just double a length of wire and
twist until it looks right, but I don't feel that the results of
that process are very good. I've embedded a video on my website to
show how I make what I regard as a much better alternative.
The process is quite simple, and I've used "found materials" to do
it for a long time, but the better the tools, the better the results.
I once made nearly twenty feet of twisted wire -- had to hang the
rig from the satellite dish, outside, and work on an extension
ladder. Fun... :)
